KillDisk

KillDisk is a generic detection name used by ESET to refer to destructive malware with disk wiping capabilities, such as damaging boot sectors and overwriting then deleting (system) files, followed by a reboot to render the machine unusable. Although all KillDisk malware has similar functionality, as a generic detection, individual samples do not necessarily have strong code similarities or relationships. Such generic malware detections usually have many “sub-families”, distinguished by the detection suffix (e.g. KillDisk.NBO, KillDisk.NCV, and KillDisk.NCX). Sub-family variants that do have strong code similarities, are sometimes seen in separate cyberattacks and thus can help researchers make connections between them.
